LADYS HATPIN.

Specification of Letters Patent.

Patented Jan. 1'7, 1922.

Application filed January 25, 1921. Serial No. 439,868.

To all whom it may concern:

Be it known that I, lVoLr HOFFENBERG, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Ladies Hatpins, of which the following is a specification.

The present invention relates to improvements in ladies hat pins. The object of the invention being to provide a hat pin which will avoid the necessity of puncturing the hat through more than one hole, thereby avoiding injury to the hat which is occasioned by many perforations being made therein.

In the accompanying drawing, Figure l is a perspective view of my invention showing a portion of the inside of the hat; Figure 2 is a similar figure showing the portion of the outside ofthe hat; Figure 3 is a cross sectional view on an enlarged scale through the pin, showing said pin and inner plate secured to the hat; Figure a the cross sectional view through the hat on a similar scale.

Referring to the drawing, 1 indicates the material of the hat through which the pin is passed and to opposite sides of this material are secured small plates 2, and 3, the plate 2 being on the inner side, and the plate 3 on the outer side. These plates are secured together by means of a tube like portion I of the plate 2, which portion passes through the material and then through the plate 3. Onto the outer end of the tube 4t is screwed a guide sleeve 5. The hat pin 6 is formed with a longitudinal groove 7, terminating short of the extreme inner end of the pin.

entering said groove 7 is a projection 8, which extends from a slidable plate 9 secured to the plate 2 by means of screws 10. These screws extend through slots 11 in the plate 9 and into said plate 2. An opening 12 is provided in the tube 4 and said pro ection 8 extends through this opening and into the groove 7. The projection is maintained in engagement with groove 7 by means of springs 1?) bearing against the plate 2 with the inner ends secured by pins 14 t0 the plate 2, while the free outer ends engage notches 15 in said plate 9. Thus at any time the pin can be detached from plate 2 by pushing against one end of the plate 9 so as to slide said plate and withdraw the projection 8 from the groove thus permitting the hat pin to be wholly withdrawn from the guide sleeve 5 and tube 4.

To place the device in an operative position the hat pin is merely passed through the guide and turned so that the inner end of the projection 8 can drop into groove 7. The pin will then always be held in place and ready to be pushed into the hair of the wearer as may be desired. lVhen the pin is withdrawn the inner end thereof lies substantially flush with the inner surface of the hat and as the inner side of the device as a whole is flat and lies close to the said inner side of the hat, there is little or no projection offered which might become entangled with the hair upon the removal of the hat.

However, the form and arrangement of the projection can be greatly varied without departing from the spirit of my invention:

I claim 1. In combination with a hat having a guide extending transversely through the side thereof, a hat pin slidable in said guide and having a groove closed at both ends, a projection movable transversely to the hat pin and adapted to enter said groove and springs adapted to move said projection into said groove substantially as described.

2. The combination with a hat, of a guide extending through one side thereof, a hat pin slidable in the guide and having a groove, the end of which adjacent to the point of the pin is closed, a projection carried by the guide and being movable into and out of said groove and spring means normally holding said projection in said groove.
